The invention relates to a medical implantable lead for monitoring and/or controlling of an organ inside a human or animal body, comprising two electrical conductors (6, 9), each connected to a respective electrode for receiving or transmitting of electrical signals from or to the organ, and a tubular header (14) in a distal end of the lead. One electrode (3) is positioned in the outermost distal end of the lead whereas the other is a ring formed electrode (16), which is mounted by means of a coupling on the outside of the header. The coupling and the header (14) are integrated into one unitary piece of an electrically insulating material having a coupling portion (15) and the coupling portion is adapted for quick fixating connection of the ring electrode to the header. The quick fixating connection is a snap fit connection. The invention also relates to a method for manufacturing of a medical implantable lead.
